Rule · RBNZ · 17 May 2022
The Reserve Bank of New Zealand finalized revisions to banking capital adequacy requirements for residential mortgages, aligning loan-to-value ratio calculations and formalizing internal models approval processes. The regulator delayed the implementation of rules reclassifying loans for borrowers with more than five properties until December 2014 to address technical concerns raised by stakeholders. Additionally, the document confirms consequential amendments to BS19, BS2A, and BS2B to reflect the Financial Reporting Act 2013 and clarifies property valuation policy requirements.
Summary of submissions and final implementation decisions of the review of bank capital adequacy requirements for housing loans (stage two) and consequential changes to BS19 Summary of submissions and policy decisions on revisions to BS2A and BS2B for Financial Reporting Act 2013 Please note that this is not a consultation document. June 2014
Background
Part I Definition issues
Definition of the loan amount in the LVR calculation
8. The exposure draft consultation proposed the following wording to ensure that standardised and
internal models banks apply a common definition of what to include in the loan amount when calculating the loan-to-value ratio. Crucially, standardised banks no longer have to add other lending to the home loan amount. This will align them better with what is the requirement for internal models banks. BS2A Updated Section 37 (1) The loan-to-valuation ratio for a residential property is calculated by the formula:
Loan-to-valuation ratio (LVR) = (loan value/property value)*100 (2) In the formula— “loan value is the total amount, as at balance date, of:
(i) all claims secured by way of first ranking mortgage over the residential property; and (ii) all undrawn commitments to the borrower that when drawn down will be secured by way of first ranking mortgage over the residential property. (3) Lending facilities that are treated as unsecured lending and not tied to, nor managed as part of, the residential mortgage, such as credit cards or personal loans, are not normally secured over the residential property and do not need to be included in the LVR calculation.” BS2B New section 4.150A “The loan-to-valuation ratio for a residential property is calculated by the formula:
Loan-to-valuation ratio (LVR) = (loan value/property value)*100 In the formula— “loan value is the total amount, as at balance date, of:
(i) all claims secured by way of first ranking mortgage over the residential property; and (ii) the EAD amount of any off-balance sheet exposures secured by way of first ranking mortgage over the residential property and consistent with sections 4.155 to 4.158. Lending facilities that are treated as unsecured lending and not tied to, nor managed as part of, the residential mortgage, such as credit cards or personal loans, are not normally secured over the residential property and do not need to be included in the LVR calculation.”
9. Most submissions either agreed to the proposed wording or did not comment on it. One
submission argued that the text should clarify that secured lending, e.g. motor vehicle loans with security over the car, are also excluded from the definition if not tied to or managed as part of the mortgage loan.
“A property valuation policy means a policy governing how a property value is determined for a residential mortgage loan that - (i) is approved by a bank’s board of directors; (ii) includes the requirement that only the purchase price or property valuations by independent valuers or a professional valuation service are used for the purpose of calculating the loanto-valuation ratio;(iii) includes guidance on the appropriate credit risk-related use of different valuation products; (iv) includes guidance on the use of the purchase price of a residential property; (v) includes guidance on the determination of the origination date; and (vi) ensures that its application is invariant to the direction of the movement of residential property prices.” “independent valuer means a person who is not associated with a person who has an interest in the residential property for which a valuation is made and who is: (i) a registered valuer as defined in the Valuers Act 1948; or (ii) another person approved to provide valuation services by rules made under the Rating Valuations Act 1998:” “For the purpose of this section, a professional valuation service means a service that provides either a statistical or modelled valuation based on market sales price data or a valuation carried out by appropriately qualified valuation personnel overseen by an independent valuer.” Other clarifications to the LVR requirements
14. This part of the exposure draft consisted of a minor word change in BS2A to explain that
mortgages in excess of a 100 percent LVR should be treated as residential mortgage loans and not as other assets. This was a minor change and no submission commented on this aspect. A second minor change involved the deletion of the word fully in Section 43 of BS2A. There was also no comment on this proposal. Neither wording has been changed as a result. BS2A New Table 4.11 Loan-tovaluation ratio Risk weight (%) If there is lender’s mortgage insurance that qualifies under
section 38
If there is no lender’s mortgage insurance or lender’s mortgage insurance that does not qualify under
section 38
Does not exceed 80%
35 35
Exceeds 80% and not 90%
35 50
Exceeds 90% and not 100%
50 75
Exceeds 100 % 100
And to be deleted
Section 36 (2)
“Residential mortgage loans with loan-to-valuation ratios of more than 100% are treated as “other assets” and risk weighted at 100%.” Also new Section 43 (e)
“..a loan fully secured by a first ranking mortgage over a residential property used primarily for residential purposes either by the mortgagor or a tenant of the mortgagor.” (section 43 (e)) Distinction between a residential mortgage exposure and other types of exposure
15. This part of the consultation received the most feedback. It concerned the boundary between
residential mortgage loans and other types of exposures. Most respondents raised concerns about the clarification that customers with multiple properties ought not to be included in the residential property (retail) asset class. The majority of submissions accepted that these customers were different from owner occupier mortgage borrowers but raised technical issues about the proposed rule and the implementation timeline. A small number of submissions commented on the marketability criterion and the meaning of the term ‘predominantly’. Proposed wording of exposure draft consultation BS2A section 43 (e) “Residential mortgage loan” means a loan secured by a first ranking mortgage over a residential property used primarily for residential purposes either by the mortgagor or a tenant of the mortgagor. A loan may not be classified as a residential mortgage loan if:
a) the mortgaged property would be marketed as a farm or a commercial property; or b) the mortgaged property is predominately used for farming or commercial activities; or c) the principal or interest payments are predominantly serviced from the income generated by the use of the property for farming or commercial activity, except for rental income unless (iv) applies. d) if the bank has recourse to, or is aware of, more than five properties owned and let by the borrower directly or through a company or any other ownership structure of the borrower, and the loan is predominantly serviced from the rental income those properties generate, then the loan can no longer be classified as a residential mortgage loan but should be classified as either income producing real estate or SME retail lending. The bank is required to verify whether the customer has any other rental properties or residential mortgage loans with another lender or lenders as part of its credit origination process. For the purpose of this section, predominantly means more than 50 percent. BS2B section 4.7 (a) Exposures secured by residential mortgages Residential mortgages are eligible for retail treatment regardless of exposure size. “Residential mortgage loan” means a loan secured by a first ranking mortgage over a residential property used primarily for residential purposes either by the mortgagor or a tenant of the mortgagor. A loan may not be classified as a residential mortgage loan if:
a) the mortgaged property would be marketed as a farm or a commercial property; or b) the mortgaged property is predominately used for farming or commercial activities; or c) the principal or interest payments are predominantly serviced from the income generated by the use of the property for farming or commercial activity, except for rental income unless (iv) applies.
d) if the bank has recourse to, or is aware of, more than five properties owned and let by the borrower directly or through a company or any other ownership structure of the borrower, and the loan is predominantly serviced from the rental income those properties generate, then the loan can no longer be classified as a residential mortgage loan but should be classified as either income producing real estate or SME retail lending. The bank is required to verify whether the customer has any other rental properties or residential mortgage loans with another lender or lenders as part of its credit origination process. For the purpose of this section, predominantly means more than 50 percent.
16. Although most submissions commented on the clarification that owners of multiple properties
should not be included in the residential mortgages asset class (BS2A Section 43 (e) and BA2B
4.7 (a) d respectively), there were also a few comments on the other points listed above. A couple
of respondents enquired how to determine whether a property would be marketed as a residential property or as something else (point a). One submission asked whether the marketing at the last sale would be sufficient, while another asked whether zoning should be used as a guide. Another submission requested clarification about what the term predominantly meant in the context of a property’s use (point b).
17. A few submissions argued that the income producing real estate asset class would be unsuitable to
customers with multiple properties as, in their opinion, it should be reserved for specialised lending (where there is nor recourse beyond the assets and its cash flows). It was also pointed out that using IPRE would significantly increase the risk weight on those loans. Some submissions argued that customers should either be treated as SME Retail (as proposed) or if the bank’s exposure to the customer exceeds $ 1m, as SME corporate. Others stated that they currently did not have an internal model for customers with more than five properties and that new models would have to be commissioned (and of course approved by the Reserve Bank). One bank estimated that this would take 18 months.
18. Most submissions highlighted issues with identifying how many properties existing customers
have and verifying a customer’s number of properties at the point of mortgage origination. Questions were raised as to whether the five properties had to be located in New Zealand and how to treat part-ownership structures, i.e. do they count in proportion to the share of the customer’s stake in the ownership structure? Related to these issues were questions about the treatment of customers that cross the five properties threshold in either direction, i.e. from four to five properties or conversely from five down to four, and how to manage those customers.
19. One submission argued that privacy laws prevented it from enquiring from existing customers
how many properties they owned and that the rule should only apply to new customers.
20. Some banks highlighted that they would have to retrain staff on how to treat customers that fall
within the five plus category and gave an indicative timeline of six to nine months. It was argued that by not being in the retail asset class, customers would have to be managed on an individual basis which required the bank to obtain more detailed information. That and the higher risk weights could lead to a higher pricing of those loans. The two submissions from parties involved in property investment activity also highlighted concerns about the potential for an increase in the cost of residential property loans for investors with five or more properties.
21. Banks also made suggestions as to how customers with more than five properties could be treated
in the interim. Amongst the suggestions made were proposals to start applying the rule to new customers only in the interim and to allow more time for existing customers with more than five properties to be identified. An internal models bank proposed to use the standardised approach for
this group of customers until new models have been developed. Two internal models banks proposed to use an income threshold instead of the count based five properties threshold2 . That would mean taking loans that are predominantly (i.e. more than 50 percent) repaid from the rental income a residential property generates out of the (retail) residential mortgage asset class and treating them as SME retail or corporate loans. Another internal models bank disagreed with this proposal when asked by the Reserve Bank. The majority of submissions that commented on this aspect of the exposure draft consultation, including all internal models banks, asked the Reserve Bank to delay the introduction of the rule for existing customers at least.
22. The Reserve Bank understands the technical difficulties banks have in implementing the rule and
proposes to delay the introduction of the clarified requirement to allow for more time to consider the issues that have been raised and to fine-tune the nature of the requirement. That said, some of the timelines proposed by respondents, such as delaying the implementation by up to 18 months, are unduly lengthy. It has therefore been decided to postpone the implementation of the capital treatment of customers who own and let out multiple properties, i.e. property investors, until December 2014.
23. The Reserve Bank accepts that determining whether a property is ‘predominantly used for
farming or commercial activities’ and how a property may be marketed may not always be straight forward. However, the latter criterion was proposed by one of the respondents to the previous consultation. Since the main purpose of this section is to distinguish residential from other types of properties, the order of the criteria has been amended to clarify that farm and commercial properties ought not to be counted as residential mortgage properties. A property’s marketability and the income used for repaying the mortgage loan are the key criteria for determining a property’s use. New text in BS2A and BS2B BS2A section 43 (e) new additions “Residential mortgage loan” means a loan secured by a first ranking mortgage over a residential property used primarily for residential purposes either by the mortgagor or a tenant of the mortgagor. A loan may not be classified as a residential mortgage loan if the mortgaged property is predominately used for farming or commercial activities. Without limitation, a property will be considered to be predominately used for farming or commercial activity if:
i. the mortgaged property would be marketed as a farm or a commercial property;
or
ii. the principal or interest payments are predominantly serviced from the income
generated by the use of the property for farming or commercial activity, except where that income is rental income and the property is used for a residential purpose. For the purpose of this section, predominantly means more than 50 percent. BS2B section 4.7 (a) Exposures secured by residential mortgages Residential mortgages are eligible for retail treatment regardless of exposure size. 2 One bank made this proposal in a bilateral discussion with the Reserve Bank subsequent to having submitted their formal consultation response.

Part II Internal models requirements
24. This part of the exposure draft requested feedback on the wording of the proposal to incorporate
the process criteria for internal models changes in BS2B and the establishment of a compendium of approved models between the Reserve Bank and each of the internal models banks. There was general agreement on the proposed wording but a few submissions asked for clarification on a small number of aspects. Some of the required clarifications on the models compendium may require further discussions with banks. Given the importance of accurately recording information in the compendium, the Reserve Bank is amenable to delaying its introduction by three months until 01 October 2014.
25. Some of the banks that commented on the formalisation of the model change requirements stated
that calculating the capital outcome under the standardised approach was currently being done outside the capital engine and therefore less robust. They requested clarification that this would be acceptable to the Reserve Bank. Other comments requested the deletion of the requirement to report changes in model parameters due to significant portfolio shifts to the Reserve Bank since, according to that submission, it was not sufficiently clearly articulated and would become visible by changes to model estimates, structures or judgements in any case, and to clarify whether risk weighted assets and capital impacts should be calculated at the four data points. One bank asked how the quarterly window process the Reserve Bank has been operating would be captured by the requirement.
26. A couple of respondents sought further explanation on when the compendium should be updated
and how RWA and capital information should be captured. One of those submissions remarked it assumed that further detail would be included in the conditions of registration.
27. The Reserve Bank accepts that calculating the outcome under the standardised approach might
have to be done outside the capital engine for now and that as long as banks do that on a genuinely best endeavours basis its requirement is met. Long term, the Reserve Bank strongly expects banks to be able to carry out the calculation in the capital engine. The Reserve Bank is, however, not minded to delete the requirement that it be notified of large portfolio shifts. They help bring to our attention changes in risk weighted assets and can provide the explanation as to why they are happening.
28. The requirement to calculate impacts at four consecutive data points refers to the risk weighted
assets and capital impacts. This requirement has been in place for almost one year now.
Next steps
31. All changes except the asset class treatment of customers with more than five properties and the
introduction of the models compendium will be implemented on 01 July 2014. The Reserve Bank will consult with the banks on the necessary changes to the conditions of registration in the coming days.
32. The Reserve Bank will arrange workshop with the banks on the outstanding items to discuss the
technical detail around their implementation. We currently envisage that the internal models compendium will come into effect on 01 October 2014. The target date for the asset class treatment of customers with more than five properties owned and let out is December 2014.
Part III Consequential updates to BS19
33. The Reserve Bank proposed changes in the definitions of a number of terms in the Handbook
document BS19, “Framework for Restrictions on High-LVR Residential Mortgage Lending”. These terms are defined by reference to BS2A and BS2B, and the updates to BS2A and BS2B allow greater consistency between the definitions applicable to IRB banks and those applicable to other banks. So corresponding updates to the definitions in BS19 allow more consistent application of the LVR policy between the IRB banks and the other banks.
34. Submissions were generally supportive of the proposed changes. Some banks noted that the same
concerns about timing arose with BS19 as with BS2A and BS2B. However, provided that banks are able to switch to the new definitions in BS2A and BS2B apart from the deferred change in the residential mortgage classification as described above, the Reserve Bank believes that banks will be able to use the new definitions in BS19 corresponding to the first set of BS2A and BS2B revisions from the same date.
35. One bank noted that it can have estimates of over 100% for Exposure at Default (EAD) on its
residential mortgage loans, which means that the “loan value” as defined in BS2B can be greater than the total of on-balance-sheet claims and off-balance-sheet exposures relating to the property. This bank feels that for the purposes of the LVR policy (as opposed to capital adequacy), it is sufficient for the loan value to include the full amount of the off-balance-sheet exposures, but not more than that.
36. The Reserve Bank agrees with this point and has revised the definitions of “loan value” and
“loan-to-valuation ratio” for IRB banks accordingly. The revised new definitions are as follows – “loan value”, for a residential mortgage loan,— (i) if made by an IRB bank, has the same meaning as “loan value” as defined for the purpose of defining “loan to valuation ratio” in section 4.150A of BS2B for the residential property on which the residential mortgage loan is secured (except that when incorporating any offbalance sheet exposures in the loan value, the bank may apply a credit conversion factor of 100% rather than using its own EAD estimates); and (ii) if made by any other registered bank, has the same meaning as “loan value” as defined for the purpose of defining “loan-to-valuation ratio” in section 37 of BS2A for the residential property on which the residential mortgage loan is secured “loan-to-valuation ratio”, in relation to a residential mortgage loan,— (i) if made by an IRB bank, has the same meaning as in BS2B (except that if the bank has varied the calculation of “loan value” as permitted in these definitions, the bank must use that loan value in calculating the loan-to-valuation ratio); or (ii) if made by any other registered bank, has the same meaning as in BS2A
(b) the term “subsidiary” has the same meaning as in paragraph 5 in “Part 2 – Capital Definition”. (2) Replace the end section of paragraph 6.1 in BS2B with the following – For the purposes of these definitions,— (a) the terms “parent”, “associate” and “joint venture” are determined in accordance with generally accepted accounting practice, where “generally accepted accounting practice”— (i) has the same meaning as in section 8 of the Financial Reporting Act 2013 (unless paragraph (ii) applies); or (ii) means generally accepted accounting practice within the meaning of section 3 of the Financial Reporting Act 1993 if the Financial Reporting Act 1993 applies to the bank; (b) the term “subsidiary” has the same meaning as in subparagraph 2.2(o) in “Part 2 – Capital Definition”. (3) Replace sub-paragraph 119(1)(b) in BS2A (Part 9) with the following – “generally accepted accounting practice”— (i) has the same meaning as in section 8 of the Financial Reporting Act 2013 (unless paragraph (ii) applies): or (ii) means generally accepted accounting practice within the meaning of section 3 of the Financial Reporting Act 1993 if the Financial Reporting Act 1993 applies to the bank; (There is no equivalent to this revision needed in BS2B.)
Part V
Anti-avoidance and ‘unsecured’ debt linked to residential mortgages (Report back on December 2013 consultation paper) Unsecured debt linked to residential mortgages
43. Most submitters agreed that it would be appropriate, given that most unsecured lending to a
mortgage customer is not counted in that customer’s LVR, for BS19 to note that unsecured lending to mortgage customers under terms that “are substantially different to that which would apply under normal risk management practices or are determined in reliance of the security provided by an all-obligation mortgage” could be considered avoidance activity.
44. Several submitters noted that banks may offer terms on unsecured debt to mortgage customers
that reflect improved information flows about the customer resulting from the broader view of the customer’s business, or to provide a “loyalty incentive”.
45. One submitter suggested that if products were constructed on a basis that made it difficult for
them to be an effective way to avoid the LVR policy, they should not be considered avoidance. RBNZ response
46. We agree that offering marginally better terms to mortgage customers is not necessarily avoidance
or contrary to normal risk management practice.
Response
52. The Reserve Bank considers the planned anti-avoidance approach is indeed workable and will
pursue it. If indicators suggest there is surprising growth in unsecured debt and it can be linked to mortgage customers, the Reserve Bank could consider more onerous regulatory options.
53. The Reserve Bank agrees that it will not always be apparent when unsecured credit has indirectly
facilitated savings, for example through being spent down while salary is saved for a deposit. (Indeed, this is part of the reason that we have additional anti-avoidance clauses seeking to ensure that mortgage customers do not get highly preferential access to non-mortgage debt, as this could make the LVR policy ineffective.) We are not asking banks to conduct flow of funds analysis on individual customers, instead to use their existing practices to identify any attempts to more directly use unsecured debt to fund a deposit. Data on anti-avoidance
54. Submitters agreed that banks would be able to provide data on non-mortgage credit extended to
mortgage customers, although some time and resources would be required. One submitter suggested the Risk Managers Roundtable (an informal gathering of bank risk officers) would be a useful point for coordinating on the nature and standards of the data.
55. The Reserve Bank is pleased that it appears feasible to obtain data on non-mortgage debt of
mortgage customers and will consider this against other data collection priorities. The Reserve Bank accepts that templated regular provision of this data may take some time to arrange, but this should not be of concern unless there is evidence of a change in industry practice in this area (in which case we may need to seek one-off data in this area more urgently).
